👉 Surfaces are surfaces in geometry, which describe the surface of objects or surfaces. They can be defined as flat surfaces that have a smooth boundary (boundary) and are not curved. Surfaces may have multiple layers, including top, bottom, front, back, sides, etc. In mathematics and physics, surfaces are fundamental concepts used to analyze various physical phenomena such as fluid dynamics, heat transfer, sound propagation, and more. They are also important in modeling the Earth's surface and space around it
